TRACTOlEl ATTACHMENT FOR VEHICLES.

' 'Specification of Letters Patent. Partantd Sept. 10, 1918.

Application filed November 25, 1916, Serial No, 133,374. Renewed December 29, 1917. Serial No. 209,603.

To all whom t mag/concern.'

Be it known that we, JOHN SAiN'rEVE and LAWRENCE LEwIs, citizens of the United States, residing at Belleville, in the county of St. Clair, in the State of Illinois, have jointly invented certain new and useful Improvements in Tractor Attachments for Vehicles, of which the following is a specification. i f

rlhis invention relates to improvements in tractor attachments for vehicles and more particularly to a device adapted for attach-` ment to a plow, binder, reaper or the like to assist the draft animals with the work of propelling such vehicles. The invention comprises a drive wheel driven throughthe medium of manually operable rock bars which are so connected to the drive wheel as to insure a steady and even movement of the same. With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described in this specilication, pointed out in the appended claims and illustrated in the accompanying drawing which forms a part of the specification and in which- Figure 1 is a side elevation of the device.

Fig. 2 is a plan of the same.

Like reference characters denote corresponding parts in both views.

The reference numeral 1 denotes the tongue which at its front end carries a coupling 2 adapted for engagement with the vehicle to be driven. The beam at its rear end is formed with the depending arms 3 mounted upon the axle 4 whereon the rock bars 5, 6 are fulcrumed, said rock bars carrying, respectively, the pawls 7 8 that ride upon and engage with the teeth of the ratchets 9, 10 which are fast upon the said axle 4 which is also the axle of the large spur-drive wheel 11, said drive wheel being positioned between the ratchets 9, 10 and fast upon said axle. Each rock bar pivotally carries a leg 14 which is pointed at its free end and formed with offset 15 at its pivoted end for engagement with the terminalheel 16 of the rock bar whereby the movement of the legs 14: about their pivots is limited.

The rock bar '5 is connected, at its front end, by pitman 17 with an operating bar 18 pivoted at one end upon a pin 19 carried by tongue 1 and terminating at its free end in a handle 20. The rock bar 6 is connected,

at its front end, by pitman 21 to a rocker 22 fulcrumed upon apost 23 depending from said tongue 1, said rocker being connected by link24 lto a second operating bar 25 pivoted upon said pin 19 and terminating at its free end in a handle 26. The operator walks behind the device and alternately raises and lowers the operating bars 18, 25 thereby simultaneously raising and lowering or rocking the rock bars 5, 6,. Upon the down stroke of the bar 25 and the up stroke ofthe bar 18 the forward ends of the rockers 5,6 are raised and the rear or heel-carrying ends of the same lowered thus moving the pawls 7, 8 over their ratchets and driving the legs 14 into the ground impelling the device forward. Upon the up stroke of bar 25 and the down stroke of bar 18 the forward ends of the rockers 5, 6 are depressed and the legs 14 raised out of the ground and the pawls driven into operative engagement with' their ratchets impelling the device forward.

What is claimed is 1. In a tractor attachment for vehicles, a drive wheel fast upon its axle, a tongue fulcrumed upon said axle, rock bars fulcrumed upon said axle, manually operable means carried by said tongue and connected to said rock bars for actuating the same, connection between said rock bars and axle whereby the rock motion of the former is transmitted to the said axle in the form of intermittent rotary motion and legs pivotally carried by said rock bars.

2. In a tractor attachment for vehicles, a drive wheel fast upon its axle, a tongue fulcrumed upon said axle, rock bars fulcrumed upon said axle, manually operable means carried by said tongue and connected to said rock bars for actuating the same simultaneously, pawl and ratchet connection between said rock bars and axle whereby the rock motion of the former is transmitted to said axle in the form of intermittent rotary motion, legs pivotally carried by said rock bars and means terminally carried by said rock bars for engagement with said legs to limit their pivotal movement.

3. In a tractor attachment for vehicles, a drive wheel fast upon its axle, a tongue fulcrumed upon said axle, rock bars fulcrumed upon said axle, manually operable bars pivotally carried by said tongue, connection between said bars and said rock bars for transmitting motion from the former to the latter, and power transmission mechanism connectingL said rock bars and axle whereby uniform rotary movement is imparted to the latter. I

" 4. In a tractor attachment for vehicles, a drive wheel fast upon its axle, a tongue fulcrumed upon said axle, rock bars fulcrumed upon said axle, manually operable bars pivotally carried by said tongue for reciprocal movement, connection between said bars and said rock bars whereby the movementof the former is transmitted to the latter ina uniform manner, and transmisl sion mechanism operatively connectingl said.

drive wheelvfasty upon its axle, a tongue fulcrumed upon said axle, rock bars fulcrumed upon said axle, operating bars pivotally carried by said tongue, connection between said operatingwbars and rock bars 'for transmitting motion from one to the other, pawl and ratchet connection between said rock bars and axle, legs pivotally carried by said rock bars for intermittent engagement with the ground, and means terminally carried by said rock bars for engagement with said legs to limit their pivotal movement.

In testimony that we claim the foregoing as our own wehave hereto affixed our signatures in the presence of two subscribing Witnesses. v
